Labradorite Blue Australe: complete guide

History and origin

Madagascar is known for several stones rich in labradorite, a feldspar that produces the optical phenomenon of labradorescence. Blue Australe is one of the most sought-after varieties for the intensity of its blue flashes and is commercially treated as granite. It is a high-end material, produced in limited quantities and used in luxury projects. Marmi di Carrara supplies it on request.

Look and veining

The background is dark blue-grey, with large labradorite crystals that, depending on the light and viewing angle, flash electric blue and sky blue. Each slab has a different distribution of flashes, so selection and possible book-matching are important. Polishing is the finish that enhances the iridescence; matt finishes greatly subdue it.

Technical properties (indicative)

Recommended uses

Ideal for statement kitchen worktops, islands, bar counters, bathroom vanity tops, wall cladding and tables. It is technically hard-wearing, but the value of the material makes it better suited to visible surfaces than to high-traffic floors. To make the most of the iridescence, the lighting must be carefully planned.

Care and maintenance

Clean with a neutral detergent and a soft cloth; a stain-proofing impregnator is recommended, especially on kitchen worktops. Avoid abrasive products, which can dull the polish and dim the flashes.

Pairings

• polished steel and chrome
• ebonised or black lacquered wood
• neutral-light LED grazing lighting
